Sampling with Partial Replacement and Stratification
Abstract:Sampling with Partial Replacement (SPR) is extended to double sampling for stratification on three occasions based on the two-occasion case presented by Bickford et al. (1963). Ware and Cunia's (1962) unbiased estimator of net change is extended to double sampling for stratification on two and three occasions. A closed form solution is presented for the two-occasion case. However, the net change estimator in the second-occasion case requires solving a system of seven equations. The estimators presented make it possible to use Sampling with Partial Replacement on two or three occasions, with simple random sampling, stratified random sampling, or double sampling for stratification; and, for estimation of current attributes, their net change between occasions, and components of growth. For. Sci. 40(1):30-46.
